Losing FA Cup finalists Chelsea have come under fire after failing to wear black armbands in honour of the Manchester attack victims.

The west Londoners were beaten 2-1 by Arsenal in yesterday's showpiece at Wembley Stadium, and sparked outrage when they emerged in the first half without the bands.

This was corrected in the second half, but there was further controversy when Chelsea's Victor Moses removed his armband and dropped it after being sent off in the 68th minute.

Social media users were quick to point out the blunder, with league champions Chelsea being described as a 'vile club with no class'.
